DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illuminated waveform switch used for electric and electronic devices and control devices, general-purpose machines and the like.

[0002]

2. Description of the Related Art In a conventional full-illuminated waveform switch, it is necessary to arrange a light-emitting body at the center of a switch body in order to make the illumination of a button uniform. In addition, an incandescent lamp or a neon lamp is used as a light source from the relation of light quantity, and a waveform button is configured to surround these light sources.

[0003]

In a conventional full-illuminated waveform switch, it is necessary to arrange a light emitter at the center of the switch body in order to make the illumination of the buttons uniform. FIG. 4 is a sectional view of a conventional full-illuminated waveform switch. Since the light emitter is located in the center of the switch,
Since the contact parts are configured to be small under the influence thereof, there is a disadvantage that it is difficult to secure a large switching capacity. In addition, the button border tends to create shadows on the illuminated surface, and if a light emitting diode is used as the illuminant, the brightness of the button is insufficient, so it is necessary to improve the translucency of the button. Could be seen. The present invention can eliminate these disadvantages. In addition, in the case where the light emitting diode is used as the light emitting body, there is a disadvantage that it is expensive because a plurality of elements are arranged in order to compensate for the insufficient light quantity. The present invention has been made to solve the above problems.

[0004]

Means for Solving the Problems The buttons of the illuminated waveform switch are divided into upper and lower parts, and the upper material is a light-transmitting member having a characteristic of diffusing light, and the lower material is a non-light-transmitting member having high reflection efficiency. The light emitter is disposed on the side surface or obliquely below the button so that the upper translucent member receives the light of the light emitter from the side surface or obliquely below.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS When a button is tilted and a light emitter is turned on, a light-transmitting member above the button guides light from the side or obliquely below to the entire button surface to form a fully illuminated waveform switch.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present embodiment will be described below in detail with reference to the drawings. FIG. 1 is a sectional view showing a first embodiment of a full-illuminated waveform switch according to the present invention, and FIG. 2 is an exploded perspective view thereof. In these figures, a light emitting diode is used as the light emitting body 15, and the button 1 is a translucent member 2 having the property of diffusing light by filling the upper part with glass beads or the like, and the lower part of the button 1 is made of titanium white or the like. A light-receiving portion 4 is provided below the left and right sides of the light-transmitting member 2 for receiving light from a light-emitting body. The light-receiving portion 4 is formed of a non-light-transmitting member 3 filled with a material that promotes light reflection. I have. The button 1 may be formed by two-color molding, or by bonding upper and lower separate parts in a later step or by fitting them together. Depending on the method of construction, a reflective film may be sandwiched between upper and lower members. The brightness of the button surface can also be improved. Further, a button pin hole 5 penetrates the center of the button 1 and a coil spring 17 for applying a contact force and a sliding rod 18 are provided below the button pin hole 5.
Is formed. Then, the button 1 is tiltably swaged by a housing pin hole 8 and a pin 20 of a housing 7 constituting a switch outer part.

On the outer peripheral portion of the housing 7, a resin spring 9 and a square window portion 10 to be fitted to the case convex portion 23 are formed so that the switch can be easily attached to the panel.
Further, an inner wall 11 is formed inside the housing, and a hole 13 for guiding the terminals of the luminous body housing groove 12 and the luminous body 15 downward is provided.

In the light-emitting diode as the light-emitting body 15 of this embodiment, the terminal 16 is bent into a terminal guide groove 22 formed opposite to the outer wall of the case after the terminal 16 is bent so as to be directed straight downward. , Left and right luminous body storage groove 1
The light-emitting surface 2 is disposed to face obliquely upward. Further, the lamp terminal 24 comes into contact with the terminal 16 of the luminous body with resiliency, passes through the gap between the case 21 and the housing 7, and comes out of the square hole 14 on the side of the housing to the outside of the switch.

A contact terminal 26 integrally formed with a fixed contact 25 is provided on a case 21 formed of an insulating material.
And the common terminal 27 are caulked and fixed, and the movable contact piece 28 is incorporated to constitute a seesaw type contact mechanism.

The assembling procedure is as follows. First, the case 21 in which the contact parts are incorporated and the housing 7 in which the lamp terminal 24 is incorporated are assembled, and then the luminous body 15 is inserted from above the housing.
The button 1 containing the coil spring 17 and the sliding rod 18
Is assembled from above and stopped with the pin 20.

In the thus configured full-surface illuminated waveform switch, the light-transmitting member 2 receives the light of the light-emitting body 15 in the inclined direction while the switch is switched and tilted to one side. Due to the diffusion effect and the influence of the reflection of the non-transmissive member 3, the entire surface of the button emits light.

FIG. 3 is a sectional view showing a second embodiment of the full-illuminated waveform switch according to the present invention. By forming the cross-sectional shape of the translucent member 42 above the button 41 to be thicker on the luminous body side and thinner as the distance from the luminous body increases, the light emission condition can be made more uniform. In this embodiment, one light emitting body 55 is arranged on one side. However, the present invention does not limit the type of light emitting element and the number of light emitting elements arranged. Instead, it can be applied to various types of waveform switches.

[0013]

As described above, according to the present invention, the following effects can be obtained. (1) The button is divided into upper and lower parts, and the upper material is a translucent member having the property of diffusing light, the lower material is a non-translucent member, and the buttons are arranged on the side or oblique direction of the button. With this arrangement, it is possible to obtain an efficient, bright and uniform illuminated surface without shadows generated by edging of the button side surface. (2) Since the light-emitting body is arranged on the side of the switch, and the light from the light-emitting body is received by the light-transmitting member above the button from the side or obliquely below, the space in the switch body where the contact portion is provided is reduced. A switch with a large opening / closing capacity can be obtained because it can be sufficiently secured. (3) Since the light-emitting body is disposed on the side or obliquely below the button, and the light from this light-emitting body is received by the light-transmitting member above the button from the side or obliquely below, a small single light source such as a light-emitting diode is used. With this light source, the entire surface of the button can be efficiently illuminated, so that an inexpensive full-illuminated waveform switch can be provided. (4) By forming the cross-sectional shape of the upper member of the button to be thicker on the luminous body side and thinner as the distance from the luminous body increases, a more uniform and uniform illumination condition can be obtained. (5) The button is divided into upper and lower parts, and the upper material is a translucent member having the property of diffusing light, and the lower material is made of a non-translucent member. Since the conductive member is received from the side or obliquely below, it is possible to provide a fully illuminated waveform switch that is excellent in design without showing the components inside the switch or the shape of the light emitting body from the button upper surface. it can.
